This International Standard specifies a method for the determination of the nitrogen content and crude protein calculation of milk and milk products by the Kjeldahl principle, using traditional and block digestion methods. The methods here specified are applicable to liquid, cow (whole, partially skimmed or skimmed milk), goat and sheep whole milk, hard, semi hard and processed cheese, dried milk, milk based infant formulae, milk protein concentrates, whey protein concentrates, caseins and caseinates, excluding those containing ammonium caseinate. NOTE Inaccurate crude protein results will be obtained if non milk sources of nitrogen are present in the products here specified.
